ENDF VII.1 download

I have just installed OpenMC 0.9.0 and am trying to install the necessary cross section libraries.

The NNDC files will not properly download and install. A message says that the MD5 checksum does not match.

I have also tried to install the JEFF 3.2 libraries. While they seem to have installed correctly, I get an error when trying to use them. The error is:

*** Error in ‘openmc’: free(): invalid next size (fast)

Is there a problem with the scripts ‘openmc-get-nndc-data’ or ‘openmc-get-jeff-data’?

Can you please help me with this?

Respectfully,

Shawn Wachter
